More than 5,000 volunteers collected 150,000 pounds of trash at 75 sites across San Diego County over the weekend, organizers of the annual Creek to Bay Cleanup said on Monday.

Workers coordinated by I Love A Clean San Diego removed typical items such as cigarette butts and plastic bags along with a few head-scratchers: a bathroom sink, AstroTurf and an Easy Bake oven.

Participants noted an unusually large amount of tires at cleanup sites, something organizers linked to heavy stream flows this winter after several large rain storms.

The day of garbage collection also included mural painting, native planting, brush maintenance and general park upkeep.

"It's grown from just a cleanup to a ... beautification event," said Morgan Justice-Black at I Love a Clean San Diego.

The group coordinates two major volunteer events each year, the Creek to Bay Cleanup in April and Coastal Cleanup Day in September. Through these and other smaller-scale efforts, volunteers typically remove 500,000 pounds of trash each year.
